Combat Energy is produced throughout the body; although its core is in the chest, that's not a special location, but rather a concentration area of Combat Energy. Even if it's destroyed, the Combat Energy can't be completely eliminated.
Therefore, dealing with these warriors, the best way to completely deprive them of their combat power is to sever the tendons in their hands and feet.
As long as these force-exerting points are destroyed, then it doesn't matter how strong the opponent's Combat Energy is—they'll find it difficult to engage in combat again.
